rovetherr thanks for the info.I remain perplexed however as to how track can be classed for various speeds. Is it really just visual? therefore subjective? I've looked at lots of track all over the eastern u.s. Can't tell if 10 or 20mph is appropriate just by looking. for example, 3 new ties per 40' retain guage with 286k cars at 10mph. Never ran anything on our private trackage above 10 mph so i'm not trying to posture as knowledgeable. But back to my original question. why doesn't pas run the oil trains at 20mph? ken patrick
